Answer:
12 ft x 25 ft
Step-by-step explanation:
If L is the length and W is the width:
L = 2W + 1
300 = LW
Substitute:
300 = (2W + 1) W
300 = 2W² + W
0 = 2W² + W − 300
0 = (2W + 25) (W − 12)
W = 12
L = 2W + 1
L = 25
The rectangle is 12 feet wide and 25 feet long.
Answer: 21 dogs
Step-by-step explanation:
We can set up a ratio.
Let x be the number of dogs.

We can cross multiply.
42 = 2x dogs
Therefore, there are 21 dogs
There will be 18 exterior angles, each of 360/18 = 20 deg. So each interior angle, which is supplementary to the exterior angle will be 180–20 - 160 deg. The sum of the 18 interior angles = 18*160 = 2880 deg.
